ACCUMULATOR.

Application ied September '27, 1907.

the accumulator for the purpose ot aii'oiding l a constant supply of energy for some specific purpose, whereas the supply of energy to the accumulator may be intermittent.

Some steam engines are used under circumstances and conditions where t-heir use is intermittent and, irregular, and it it is desired to use the exhaust steam from such engines to operate secondary engines or motors which may be required to operate continuously, it is necessary to provide some receptacle for receiving the exhaust steam Where it may collect and from which it may be supplied to the secondary motor. It would require a receptacle of very large capacity to receive and hold such exhaust steam in the form of steam, as the steam must be permitted to expand until its pressure is small to prevent an excessive hack pressure upon the primary engines.

This invention has for its object to provide a simple and comparatively inexpensive apparatus. by which the heat in the exhaust steam may be utilized in furnishing a steady supply of vapor to operate a secondary engine.

iications in the arrangement of the inlet and outlet pipes.

Refer to Fig. 1 of the'drawings, the numeral 1 designates a casing made ot steel or iron plate, or any suitable material, with the interior of which communicates the inlet pipe 2 and the outlet pipe 3. The diaphragms 4 andv 5 are located within the casing 1, being spaced from the ends 6 and 7 thereof, and these diaphragms are provided with apertures in which are inserted tubes 8, which tubes afford free communication between th`e spaces 9` and 10 formed 1 respectively between the diaphragms t and 5 andthe ends ot the casing 6 and 7. The pressure gage 11 is provided for indicating the pressure existing within the chambers 9 and 10 and within the pipes 8, a second pressure gage 12 being provided for indicating the pressure existing around pipes'S within. the casing between the diaphragme i and 5. The end 6 is provided with a 'safety valve 13, which may be adapted to blow at a. predetermined pressure,`and the space within the`- casing between the diaphragms a and 5 is also provided with a satety valve 14, `which may also be set to blow at a predetermined pressure, Wherebyfzthe safety of the casing 1 against explosion is assured. The numeral 15 designates a drip pipe which may be pro vided with a stop cock 16, by which any water of condensation w iich has, accumulated on the bottom i `may be drawn ott'.

The numeral `17 designates a pump which may be operated from any suitable onconf venient source of power, and with this puin is connected a suction pipe 1S, which cou municates with the space 10, and a discharge pipe 19, which extends within the space 9 above the diaphragm 4, and is preferably provided with a rose head 20, or some suit able spraying device. The outlet pipe 3 is shown as being smaller than the inlet pipe 2, and the casing 1 is surrounded with heat insulating material 21, as is also the pump 17 and pipes 18 and 19, while the pipes 2 and may be covered with heat insulation p Patented Mar. 11,1913. i

with water or other suitable Ifluid, and' the st ani which enters the spaces 9,'10, and the pipes 8, intermittently as it is exhausted i'nto the inlet pipe 2, imparts its heat to said water. Sonie'ot the steam will be condensed and lwill collect on the bottom 7 ot the casing' l, and this water being at the temperature ot the steam will be sprayed by the pump 17 upon the top of diaphragm 4 and will trickle down through tubes 8,

thereby imparting its. excess heat to the` water or other fluid in space 22. As now the pressure tends to decrease within t-he spaces 9 and 10 of the casing 1, due to condensation of the steam, the'boiling point of the condensed water will be lowered and reevaporation will take place affording a vapor under tension which may be utilized in a secondary motor communicating with pipe 3.

The apparatus disclosed by Fig. 2 ofthe drawings is in all respects similar to that disclosed by Fie. l, with the exception that the casing l is simply pro-vided with a grating Q5, upon which ainass of solid material, as pieces of metal or rock, sueltas limestone, 2, is adapted to be supported to actas the heat-receiving element instead of the liquid disclosed by Fig. '1,

rllhe apparatus disclosed by Fig. 3 is in all substantial respects the saine as-tliat disclosed by i, with the exception that.

instead of the inlet pipes 2 and 3 being separately connected with the interior of the shell l, they are in communication with each other by means ot the T 27, which also coniniunicates with the space 9 within the casi. The :.:aiiety valve i3 is connected tothc side instead of the top of the casing L The apparatus disclosed by Fig. 4 is the saine as that disclosed by Fig. 3, with the exception that the T 27 communicates with the space 10 within the casing 1 instead ot with the space 9. There is no means shown to withdraw water from the bottom of the casing.

The apparatus disclosed by Fig. 5 is in all substantial particulars the saine as that. disclosed by Fig. l, with the exception rthat the inlet pipe 2 is provided with a flaring nozzle 30, the flare of which is sufficient to allow the steam passing therethrough to cX- pand to the desired pressure within the casing l, and the outlet pipe 3 is-secured to a branch 31 which communicates with this nozzle close to its expanded extremity so that the steam which passes through said branch 3l and into pipe 3, is substantially at the same pressure as the steam or vapor within the casing 1.

Each of the tive figures of the drawings illustrate apparatus which in etfect forms an enlargement or bulge of pipe 2 for the purpose described above, and it is .immaterial as to the' exact manner ot leading the steam into casing l as long to freely expand thereinto and have its heat stored therein to maintain a constant supply of vapor under pressure therein for operatingI some apparatus.
